I purchased the phone on Craigslist and everything works except for the fact that I cannot add my Google account. I get a "Couldn't sign in. There was a problem communicating with the Google servers. Try again later" message. No google account = no play store = no apps. Phone is unlocked and rooted and I know absolutely nothing about flashing, unlocking etc... It is not a google issue as I can add my account to another phone. Google, Tmobile and HTC contacted but unable to help.
